WICK-STOP FOR LAMP OR OIL-HEATER B'URNERS.

SPECIFICATION formingpart of Letters Patent No. 691,710, dated January 21, 1902.

Application tiled May 4,1901.

To all whom it may concern,.-

Beit known that I, WILLIAM A. Paulusma, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Wick-Stops for Lamp or Oil- Heater Burners; and I do hereby declare the following, when taken in connection with the accompanying drawings and the numerals of reference marked thereon, to be a full, clear,

1o and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Ifigure l, a broken view in vertical section illustrating one form of my invention applied I5 to the burner ofan oil-heater; Fig. 2, a broken view showing one mode of securing my improved wick-stop collar to the outer wick-tube of the burner; Fig. 3, a detached plan view of the collar; Fig. 4, a brokenl view, in vertical section, showing the threading of the wickstop collar and the outer wick-tube for the removable attachment of the former to the latter.

My invention relates to an improvement in lamp or oil-heater burners, the object being to provide simple, convenient, and reliable means for preventing smoking by positively limiting the upward movement of the wick beyond a predetermined and safe height.

With these ends in view my invention consists in a lamp or oil-heater burner having its outer wick-tube provided with a wick-stop collar extending into the path of the wick to limit the upward movement thereof and eX- posing the wick sufciently to leave it free to burn.

My invention further consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention as herein shown I employ an independently-formed wick-stop collar 2, adapted in internal diameter to fit snugly over the outer wick-tube 3, of which it forms an upward extension and the upper end` of which is located in the same horizontal plane as the upper end of the inner' wick-tube 3a. The upper edge of this vcollar is turned inwardly and downwardlyy to 5o form a flange 4, the edge of which is cut or Serial No. 58,762. (No model.)

notched to form a continuous series of downwardly-pitched wick-stop teeth 5, which eX- tend into the path of the wick, so as to limit the upward movement thereof, but which eX- pose enough of the entire area of its upper edge to permit the same to burn freely. The size, separation from each other, and number of these teeth may be varied as desired.

In order to provide for convenient access to the wick for trimming the same or for rubbing 6o its charred edge away, the wick-stop collar is constructed for removable attachment to the outer wick-tube. For that purpose avariety of constructions may be resorted to. As shown in Figs. l to 3, inclusive, of the drawings, the lower edge of the collar is formed with three inclined bayonet-slots 6, located equidistant from each other and coacting with three correspondingly-arranged locking-pins 7, mounted in the outer wick-tube 3. For 7o additional strength the edge of the collar is not cut through in making the slots, but struck outwardly to form'bridge-like loops 8, which straddle, as it were, the lower ends of the short legs of the slots. the collar to the outer wick-tube the short legs of the slots 6 are registered with the pins 7, after which the collar is turned so as to cause the inclined lower walls of the long legs of the slots to ride under the pins, whereby 8o the collar is drawn down into place. When the collar is thus locked to the outer wicktube, it cannot be lifted by the wick, the upward movement of which will therefore invariably be stopped at a predetermined point at which the lamp will not smoke. When the wick is lifted, it'will impinge upon and be stopped by the teeth 5 of the collar, as they are located directly in the path of its upward movement; but, as aforesaid, they expose so 9o much of it that they will not prevent it from burning freely. I do not, however, limit myself to removably attaching the wick-stop collar to the outer wick-stop by the use of the bayonet-slots and locking-pins described, as a variety of other means may, as above described, be resorted to for the same purpose. Thus I may, as shown in Fig. 4, form the lower end of the wick-stop collar 2 with internal threads and the upperend of the outer roo In applying 7s` Wick-tube 3 with external'threads, whereby the collar may be readily removed and replaced.

As herein shown, the burner is provided with a spreader 9, which may be of any approved eonstruotion, and with a cone 10, resting upon the burner-skirt 1l, which is set in the usual manner into the fount l2, which is provided with Wick-adjusting apparatus 13 of any approved character.

Although the burner shown is primarily designed to be used for an oil-heater, my improved Wiek-stop collar may be applied with equal advantage to burners designed for illuminating-lamps and in any size.

In view of the modifications shown and described, as well as those suggested, and of others which may obviously be made, I Would have it understood that I do not limit myself to the precise construction herein shown, but hold myself at liberty to make sueh changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what Ielaim as new, and desire to secure by Letters speeiieation in the presence of two subscrib- 4o ing Witnesses.

WILLIAM A. PENFIELD.
